Hi

I've configured the XMLTV to pull the Radio times uk EPG stuff,and can see some channels being populated. However not all channels are being populated and missing most Logos, and there the normal common ones like BBC 2 for example, but managed to get a less common one like 5* am I doing something wrong? has anyone else at this problem?

the EPG grabs every 3 hours using this command /usr/bin/tv_grab_uk_rt: grab /usr/bin/tv_grab_uk_rt

thanks
